This document teaches that an expansion anchor is inserted into a cylindrical borehole previously drilled by a rig and the expansion sleeve is rotated by means of a setting device inserted into the expansion sleeve while the expansion body is advancing against the tapered portion of the expansion channel. Thus, a tapered undercut is formed in the foundation. In order to cut this undercut, the aforementioned expansion sleeve of US 2707897A has a cutting element at the height of the tapered portion.
根據JP60099311U1，膨脹錨栓的膨脹體藉由膨脹體的附加元件在膨脹套筒的內螺紋中的轉動而沿軸向向前逆著膨脹通道的變細部前進。 According to JP60099311U1, the expansion body of the expansion anchor bolt advances axially against the thinned portion of the expansion channel by the rotation of the additional element of the expansion body in the internal thread of the expansion sleeve.

Preferred embodiments are given in the dependent items.
根據本發明的用於膨脹錨栓的安置設備，其中膨脹錨栓具有膨脹套筒和布置在膨脹套筒中的用於膨脹套筒的膨脹體，該安置設備構造成：-具有內驅動軸，其用於膨脹體在膨脹套筒中的軸向前進；-具有包圍內驅動軸的外驅動軸，其用於將膨脹套筒轉動驅動以及使膨脹套筒沿軸向前進到基礎中；-其中，內驅動軸在後部區域中具有***端部用於插 入衝擊鑽機中；以及-其中，外驅動軸不可相對轉動地且同時至少在界限內可沿軸向移動地支承在內驅動軸上；-以及具有能釋放的鎖止裝置，藉助鎖止裝置可暫時地限制內驅動軸相對於外驅動軸向前的軸向移動，以便將向前的軸向力從內驅動軸傳遞到外驅動軸上。 An installation device for an expansion anchor according to the invention, wherein the expansion anchor has an expansion sleeve and an expansion body for the expansion sleeve arranged in the expansion sleeve, the installation device being configured with:-an inner drive shaft, It is used for the axial advancement of the expansion body in the expansion sleeve;-an outer drive shaft surrounding the inner drive shaft is used for rotationally driving the expansion sleeve and the expansion sleeve is advanced axially into the foundation;-of which , The inner drive shaft has an insertion end in the rear area for insertion into an impact drill; and-wherein the outer drive shaft is supported on the inner drive shaft in a non-rotatable manner and at the same time at least axially movable within limits;- And with a releasable locking device, the axial movement of the inner drive shaft relative to the outer drive shaft can be temporarily restricted by the lock device in order to transmit forward axial force from the inner drive shaft to the outer drive shaft .
本發明的第一主旨可為安置設備，其允許膨脹錨栓的自鑽式以及自底切式的安置，該膨脹錨栓具有內置的膨脹體。安置設備具有內驅動軸，內驅動軸在其後側與衝擊鑽機耦合並且在其前側反作用於膨脹錨栓的膨脹體，以便相對於膨脹錨栓的膨脹套筒推進膨脹體。此外，安置設備具有外驅動軸，外驅動軸包圍內驅動軸且在其前側反作用於膨脹套筒，以便使膨脹套筒轉動地或旋轉衝擊地打入基礎中。外驅動軸與內驅動軸持久地轉動耦合，使得在安置方法的任一階段中，由衝擊鑽機施加到內驅動軸上的轉動運動能從內驅動軸傳輸到外驅動軸且又從外驅動軸傳輸到膨脹套筒上。因此，尤其膨脹套筒能夠在安置方法的第一階段中以及在安置方法的第二階段中藉助同一元件、即藉助外驅動軸轉動，在第一階段中膨脹錨栓自鑽地鑽入基礎中，在第二階段中膨脹錨栓自底切地擴張。外驅動軸至少在界限內，即至少在一定的軸向距離上沿軸向可相對於內驅動軸移動地布置在內驅動軸上，確切地說，在保持內驅動軸和外驅動軸之間的不可相對轉動的連接的情況下。基於該軸向可移動性可在安置方法的第二階段中藉由內驅動 軸的軸向負荷藉助衝擊鑽機僅沿軸向加載貼靠在內驅動軸上的膨脹體，而膨脹套筒沿軸向保持未受加載，結果是膨脹體被相對於膨脹套筒向前打入到膨脹通道的變細部的區域中且因此膨脹套筒可沿徑向擴張。因為儘管在安置方法的第二階段中兩個驅動軸在軸向上脫開但是兩個驅動軸還有轉動耦合，膨脹套筒在膨脹套筒徑向擴張時同時藉由衝擊鑽機圍繞其縱軸線轉動，結果是在膨脹套筒的圓周上轉動地刮削基礎且因此能夠以特別有效的方式在基礎中製造底切部。 A first gist of the present invention may be a placement device that allows self-drilling and self-undercutting placement of an expansion anchor that has a built-in expansion body. The setting device has an inner drive shaft which is coupled to the impact drill at its rear side and reacts against the expansion body of the expansion anchor on its front side in order to advance the expansion body relative to the expansion sleeve of the expansion anchor. In addition, the installation device has an outer drive shaft which surrounds the inner drive shaft and reacts on its front side to the expansion sleeve in order to drive the expansion sleeve into the foundation rotationally or rotationally. The outer drive shaft is permanently rotationally coupled to the inner drive shaft, so that during any stage of the installation method, the rotary motion applied to the inner drive shaft by the impact drill can be transmitted from the inner drive shaft to the outer drive shaft and from the outer drive shaft Transfer to the expansion sleeve. Therefore, in particular, the expansion sleeve can be drilled into the foundation by self-drilling in the first phase of the installation method and in the second phase of the installation method by means of the same element, ie by means of an external drive shaft. In the second stage, the expansion anchor expands from the undercut. The outer drive shaft is arranged at least within limits, that is, at least over a certain axial distance, axially displaceable relative to the inner drive shaft on the inner drive shaft, to be precise, between the inner drive shaft and the outer drive shaft In the case of a non-rotatable connection. Based on this axial movability, in the second stage of the installation method, the expansion body abutting on the inner drive shaft is only axially loaded by the impact drill with the axial load of the inner drive shaft, and the expansion sleeve is along the shaft. The direction remains unloaded, with the result that the expansion body is driven forward relative to the expansion sleeve into the area of the thinned portion of the expansion channel and thus the expansion sleeve can expand radially. Because in the second stage of the installation method the two drive shafts are disengaged in the axial direction, but the two drive shafts are still rotationally coupled, the expansion sleeve is simultaneously rotated by its impact drill about its longitudinal axis when the expansion sleeve is radially expanded. As a result, the foundation is scraped rotationally on the circumference of the expansion sleeve and therefore an undercut can be produced in the foundation in a particularly effective manner.
此外，根據本發明設有能釋放的鎖止裝置，藉助鎖止裝置在鎖止裝置的鎖止狀態中能夠暫時地阻止外驅動軸在內驅動軸上至少向後的軸向可移動性，亦即，藉助鎖止裝置能夠暫時地沿軸向固定地耦合兩個驅動軸，使得能夠從內驅動軸將至少向前的軸向力傳輸到外驅動軸上。鎖止裝置在安置方法的第一階段期間被鎖止，這具有兩個作用：首先能夠將藉由衝擊鑽機施加到內驅動軸上的軸向衝擊從內驅動軸傳輸到外驅動軸上且又從外驅動軸傳輸到膨脹套筒上，使得膨脹套筒在安置方法的第一階段能夠被旋轉衝擊地驅動，這又使得膨脹錨栓也能夠在硬的基礎中特別有效地鑽出孔。另一方面能夠藉由開始鎖止的鎖止裝置防止內驅動軸在安置方法的第一階段中就作用到膨脹體上，亦即，這可確保只有在膨脹錨栓已經打入到基礎中一段距離，此時才開始擴張膨脹套筒且製作底切部，結果是獲得特別好的局部底切部。在安置方法的緊接第一階段的第二 階段中釋放鎖止裝置且因此釋放兩個驅動軸以沿軸向相對移動，結果是，如上所述內驅動軸可在外驅動軸中推進且此時膨脹體可在膨脹套筒中前進，但是膨脹套筒無需更深地鑽入基礎中。尤其鎖止裝置也可稱為可切換的鎖止裝置。尤其該鎖止裝置能夠在鎖止位置和釋放位置之間切換及/或在鎖止裝置的鎖止狀態和鎖止裝置被釋放的狀態之間切換。 Furthermore, according to the invention, a releasable locking device is provided, by means of which the outer drive shaft can be temporarily prevented from moving at least rearward on the inner drive shaft in the locked state of the lock device, that is to say With the aid of the locking device, the two drive shafts can be temporarily fixedly coupled in the axial direction, so that at least forward axial force can be transmitted from the inner drive shaft to the outer drive shaft. The locking device is locked during the first phase of the installation method, which has two effects: first it can transmit the axial impact applied to the inner drive shaft by the impact drill from the inner drive shaft to the outer drive shaft and again The transmission from the outer drive shaft to the expansion sleeve enables the expansion sleeve to be driven by rotary impact during the first stage of the installation method, which in turn enables the expansion anchor to drill holes particularly effectively in hard foundations. On the other hand, it is possible to prevent the inner drive shaft from acting on the expansion body in the first stage of the installation method by means of a locking device that starts to lock, that is to say, this can only ensure that the expansion anchor has been driven into the foundation section. Distance, at which point the expansion sleeve is expanded and an undercut is made, with the result that a particularly good local undercut is obtained. The locking device is released in the second stage immediately following the first stage of the setting method and therefore the two drive shafts are released for relative axial movement, as a result, as described above, the inner drive shaft can be advanced in the outer drive shaft and at this time The expansion body can be advanced in the expansion sleeve, but the expansion sleeve does not need to drill deeper into the foundation. In particular, the locking device can also be referred to as a switchable locking device. In particular, the locking device can be switched between a locked position and a released position and / or between a locked state of the locking device and a state in which the locking device is released.
因此，藉由本發明提供一種安置設備，藉助該安置設備能夠將膨脹錨栓鑽入基礎中，在基礎中製造底切部且將膨脹錨栓錨固在底切部中，確切地說在連續的安置方法中進行，在該安置方法中無需更換安置設備，因此該安置方法特別簡單、就有特別少數量的步驟及/或工具且能夠特別可靠地實施。基於膨脹錨栓在底切部中的布置方式，對此能夠實現特別好的負荷值，該負荷值還對鑽孔中的可能的殘餘鑽屑相對不敏感。此外實現了根據在基礎中的不同裂縫寬度進行自動地調整。 Therefore, by the present invention, there is provided a placement device with which an expansion anchor can be drilled into a foundation, an undercut portion is manufactured in the foundation, and the expansion anchor is anchored in the undercut portion, specifically in continuous placement It is carried out in a method, in which the installation equipment does not need to be replaced, so the installation method is particularly simple, has a particularly small number of steps and / or tools, and can be implemented particularly reliably. Based on the arrangement of the expansion anchors in the undercut, a particularly good load value can be achieved for this, which is also relatively insensitive to possible residual cuttings in the borehole. In addition, an automatic adjustment is achieved according to the different crack widths in the foundation.
尤其內驅動軸適宜貼靠，較佳直接地貼靠在膨脹體上。較佳地，為了貼靠在膨脹體上，內驅動軸的前端面至少部分為自由的。 In particular, the inner drive shaft is suitable for abutment, preferably directly against the expansion body. Preferably, in order to abut against the expansion body, the front end surface of the inner drive shaft is at least partially free.
在此提及徑向方向、軸向方向及/或周向方向，以及提及轉動，應尤其關於兩個驅動軸的縱軸線，即較佳關於兩個驅動軸同軸布置的軸線。方向說明“前”和“後”以及“後部”在此應統一地關於同一軸線，其中，該軸線尤其可為兩個驅動軸的縱軸線。尤其膨脹體在膨脹套筒中的軸 向推進以及膨脹套筒沿軸向推進到基礎中可包括膨脹體或膨脹套筒向前、在同一空間方向上、尤其向前方向的絕對運動。尤其可規定，內驅動軸設置成膨脹體在膨脹套筒中沿軸向向前地推進(前進)且外驅動軸用於將膨脹套筒轉動地驅動以及將膨脹套筒沿軸向向前地推進(前進)到基礎中。外驅動軸在內驅動軸上不可相對轉動的支承在專業角度可尤其理解為，內驅動軸帶動(攜動)外驅動軸轉動。不可相對轉動的支承尤其圍繞兩個驅動軸的縱軸線來提供。因為在鑽孔過程期間衝擊鑽機的轉動方向不會定期改變，在僅一個轉動方向上不可相對轉動的布置方式就可足夠。但是較佳地，外驅動軸在兩個相反的轉動方向上不可相對轉動地支承在內驅動軸上，這在應用可靠性以及製造成本方面可為有利的。外驅動軸尤其用於驅動膨脹套筒圍繞兩個驅動軸的縱軸線轉動。***端部用於使衝擊鑽機的驅動裝置與內驅動軸耦合，尤其用於將轉動運動以及軸向衝擊從驅動裝置傳輸到內驅動軸上。內驅動軸在***端部上較佳具有攜動構型。外驅動軸較佳在軸向方向上比內驅動軸短。外驅動軸尤其構造成空心軸，由此內驅動軸能夠穿過外驅動軸。內驅動軸及/或外驅動軸較佳由也可經鍍層的金屬材料構成。內驅動軸可構造成一件或多件。同樣地，外驅動軸可構造成一件或多件。基礎較佳由礦物建築材料，尤其由混凝土構成。 The radial direction, the axial direction and / or the circumferential direction are mentioned here, as well as the reference to the rotation, in particular with regard to the longitudinal axes of the two drive shafts, ie preferably about the axes of the two drive shafts arranged coaxially. The directions “front” and “rear” and “rear” should be uniformly related to the same axis, wherein this axis can be in particular the longitudinal axis of the two drive shafts.

Advance (forward) into the foundation. The non-rotatable support of the outer drive shaft on the inner drive shaft can be particularly understood as a professional angle in which the inner drive shaft drives (carries) the outer drive shaft to rotate. The non-rotatable support is provided in particular around the longitudinal axis of the two drive shafts. Because the direction of rotation of the impact rig does not change periodically during the drilling process, an arrangement that is not relatively rotatable in only one direction of rotation is sufficient. However, preferably, the outer drive shaft is supported on the inner drive shaft in a non-rotatable manner in two opposite directions of rotation, which may be advantageous in terms of application reliability and manufacturing cost. The outer drive shaft is used in particular to drive the expansion sleeve to rotate about the longitudinal axis of the two drive shafts.

In particular, expansion anchors can also be referred to as knock-on anchors. The expansion anchor also has an expansion body arranged in the expansion channel. For anchoring, the expansion body is driven forward (driven) against the tapered portion in the expansion channel, and the expansion body expands the expansion sleeve in the tapered portion.

In particular, in the locked position, the stop element can be axially located between the outer drive shaft and the inner drive shaft in a position overlapping the outer drive shaft and the inner drive shaft. In the locked position, the outer drive shaft can strike the stop element on the front side of the stop element and the inner drive shaft can strike the stop element on the rear side of the stop element, so that the inner drive shaft faces in the middle of the outer drive shaft. The forward axial movement is restricted by the stop element. As a result, the axial movement can be restricted particularly simply and reliably. In particular, it can be provided that the inner drive shaft has a forward shoulder, preferably an annular shoulder, and the stop element in the locked position hits the rear end face of the outer drive shaft and the forward-pointing shoulder of the inner drive shaft. It can further reduce the structural and manufacturing costs and can further improve reliability. The stop element can be moved between the above-mentioned lock position and the release position, preferably in a radial direction, wherein the restriction of the axial movement caused by the lock device in the lock position in the release position is cancelled.
適宜地，安置設備具有包括貫通孔的殼體，外驅動軸和內驅動軸能轉動地支承在該貫通孔中。該殼體可構成手柄及/或用於膨脹錨栓的容納部，這可進一步改進可操作性。 Suitably, the mounting device has a housing including a through-hole in which the outer drive shaft and the inner drive shaft are rotatably supported. The housing may constitute a handle and / or a receptacle for an expansion anchor, which may further improve operability.
特別較佳的是，殼體具有用於將能沿徑向移動的止擋元件接收在釋放位置中的容納部。尤其可規定，殼體將止擋元件保持在其鎖止位置中，直至止擋元件尤其在鑽孔進程逐漸進行時沿軸向到達容納部的區域中，然後藉助彈簧 機構被擠壓到容納部中。由此可以特別簡單且可靠的方式實現在從安置方法的第一階段過渡到第二階段時自動地釋放鎖止裝置。 It is particularly preferred that the housing has a receptacle for receiving a stopper element that can move in the radial direction in the release position. In particular, it can be provided that the housing holds the stop element in its locked position until the stop element reaches the area of the receptacle in the axial direction, especially as the drilling process progresses, and is then pressed into the receptacle by means of a spring mechanism. in. This makes it possible to release the locking device automatically during the transition from the first phase to the second phase of the installation method in a particularly simple and reliable manner.
適宜地，止擋元件是尤其環形部段形的彈簧，其能夠自動地進入容納部中。根據該實施方式上述彈簧機構的彈簧力來自止擋元件本身，這能夠進一步降低結構複雜性。 Expediently, the stop element is a spring, in particular in the form of an annular section, which can automatically enter the receptacle. According to this embodiment, the spring force of the above-mentioned spring mechanism comes from the stopper element itself, which can further reduce the structural complexity.
本發明的另一較佳的設計方案是，在內驅動軸上設置至少一個凸肩以用於尤其在安置方法結束時，較佳在第二階段結束時限制內驅動軸相對於外驅動軸及/或殼體向前的移動。由此能夠以特別簡單的方式確保，膨脹體沒有過度地打入膨脹套筒中，這在負荷性能方面可為有利的。至少一個凸肩可尤其為環形凸肩。尤其上面已經提及的凸肩可為該至少一個凸肩。至少一個凸肩可設置用於止擋在外驅動軸上或用於止擋在殼體上。也可設置成至少一個凸肩用於止擋在外驅動軸上且至少一個凸肩用於止擋在殼體上。藉由兩個凸肩能夠更進一步改進可靠性。 Another preferred design solution of the present invention is to provide at least one shoulder on the inner drive shaft for limiting the inner drive shaft with respect to the outer drive shaft and the outer drive shaft, especially at the end of the positioning method, preferably at the end of the second stage. / Or the housing moves forward. This makes it possible to ensure in a particularly simple manner that the expansion body is not excessively driven into the expansion sleeve, which can be advantageous in terms of load performance. The at least one shoulder may be, in particular, an annular shoulder. In particular, the above-mentioned shoulder can be the at least one shoulder. At least one shoulder can be provided for stopping on the outer drive shaft or for stopping on the housing. It is also possible to provide at least one shoulder for stopping on the outer drive shaft and at least one shoulder for stopping on the housing. With two shoulders, reliability can be further improved.
較佳地，內驅動軸在其前端部上可達到，使得內驅動軸能夠克服膨脹體用以軸向地前進膨脹體。 Preferably, the inner drive shaft is accessible on its front end, so that the inner drive shaft can overcome the expansion body to advance the expansion body axially.
此外特別有利的是，內驅動軸在鎖止裝置的鎖止狀態下向前突出超過外驅動軸。鎖止裝置的鎖止狀態可尤其理解為鎖止裝置暫時地限制內驅動軸相對於外驅動軸向前的軸向移動的狀態及/或止擋元件位於鎖止位置中的狀態。根據該實施方式，內驅動軸在安置方法的第一階段開始時可向前突出超過外驅動軸，使得內驅動軸可構成銷，膨脹錨 栓的膨脹套筒可套接到該銷上。這實現了特別良好的對中且因此實現了可靠性及/或特別好的可操作性。此外，在該實施方式中在安置方法的第一階段和第二階段之間過渡時可提供內驅動軸的特別小的移動路徑且較佳內驅動軸在第一階段中就可已貼靠在膨脹體上。由此能夠避免突然的運動且還進一步降低安置設備及/或鑽機的負荷。 Furthermore, it is particularly advantageous if the inner drive shaft projects forward beyond the outer drive shaft in the locked state of the locking device. The locked state of the locking device can be understood in particular as a state in which the locking device temporarily restricts the axial movement of the inner drive shaft with respect to the outer drive axis and / or a state in which the stop element is in the locked position. According to this embodiment, the inner drive shaft can protrude forward beyond the outer drive shaft at the beginning of the first stage of the setting method, so that the inner drive shaft can constitute a pin, and the expansion sleeve of the expansion anchor can be sleeved on the pin.

Such a tooth has a tooth portion on the outer peripheral surface of the inner drive shaft and a tooth portion on the inner peripheral surface of the outer drive shaft corresponding thereto. This provides a particularly simple design. The peripheral teeth may be, in particular, wedge-shaped teeth.

This driving configuration realizes the shape-locking rotational coupling, that is, the rotational coupling is realized by the corresponding shape, and the corresponding shape can transmit the rotation particularly effectively. In particular, the driving configuration can have end teeth arranged on the end face side of the outer drive shaft, that is, the driving configuration can be provided as a coupling that engages via the end teeth. In this case, the mating configuration arranged on the expansion anchor and the driving configuration can be produced in a particularly simple manner. At least a part of the face teeth may preferably be a wedge-shaped tooth.

The at least one first cutting edge can particularly well assist the drilling of the expansion anchor in the first phase and the at least one second cutting edge can produce the undercut in the second phase.
至少一個第二切削刃能夠尤其沿著膨脹錨栓的縱軸線延伸且特別較佳地與膨脹錨栓的縱軸線平行地延伸。由此能夠在第二階段中藉由結合轉動與擴張來製造向前擴張的底切部。尤其在膨脹錨栓的縱向方向上看至少一個第二切削刃能夠與膨脹通道重疊。由此膨脹體能夠特別有效地沿徑向擠壓第二切削刃。 The at least one second cutting edge can extend in particular along the longitudinal axis of the expansion anchor and particularly preferably parallel to the longitudinal axis of the expansion anchor. This makes it possible to manufacture a forward-expanded undercut by combining rotation and expansion in the second stage. In particular, the at least one second cutting edge can overlap the expansion channel when viewed in the longitudinal direction of the expansion anchor. As a result, the expansion body can press the second cutting edge particularly effectively in the radial direction.

Peripheral teeth 32 are formed between the inner drive shaft 20 and the outer drive shaft 30. The peripheral teeth transmit rotational motion from the inner drive shaft 20 to the outer drive shaft 30, but do not affect the shaft on the inner drive shaft 20 To Mobility.
如尤其圖4至圖6所示，內驅動軸20構造成多件式且由兩個沿軸向分開的零件構成，亦即，由相對長的後部零件和前部零件構成，後部零件從***端部29直達殼體40中。 As shown in particular in FIGS. 4 to 6, the inner drive shaft 20 is configured in multiple pieces and is composed of two axially separated parts, that is, a relatively long rear part and a front part, and the rear part is inserted from The end portion 29 extends directly into the housing 40.
安置設備1還具有能釋放的鎖止裝置，鎖止裝置本身具有止擋元件51。止擋元件51可進入鎖止位置中，在鎖止位置中止擋元件沿軸向方向看位於內驅動軸20和外驅動軸30之間且在該鎖止位置中止擋元件沿徑向與內驅動軸20和外驅動軸30重疊。尤其止擋元件51在鎖止位置中位於內驅動軸20之前且位於外驅動軸30之後，較佳在構造在內驅動軸20上的凸肩28之前且在外驅動軸30的後端面之後。如果內驅動軸20在外驅動軸30中向前移動，而止擋元件51處於鎖止位置中，則達到內驅動軸20尤其以其凸肩28撞擊在止擋元件51上且止擋元件51又以其前側撞擊在外驅動軸30的後側上的程度。由於雙重止擋，止擋元件51阻止了內驅動軸20相對於外驅動軸30向前的進一 步軸向移動，亦即，藉由止擋元件51限定了內驅動軸20在外驅動軸30中的軸向移動，且能夠將朝前的軸向力從內驅動軸20經由止擋元件51傳遞到外驅動軸30上。圖4示出了在鎖止位置中的止擋元件51以及止擋在止擋元件51上的凸肩28和止擋在止擋元件51上的外驅動軸30。內驅動軸20在該狀態下向前突出超過外驅動軸30一段。 The installation device 1 also has a releasable locking device, which itself has a stop element 51. The stop element 51 can be brought into a locked position, in which the stop element is located between the inner drive shaft 20 and the outer drive shaft 30 as viewed in the axial direction, and in this lock position the stop element is driven radially and inwardly. The shaft 20 and the outer drive shaft 30 overlap. In particular, the stop element 51 is located before the inner drive shaft 20 and after the outer drive shaft 30 in the locked position, preferably before the shoulder 28 formed on the inner drive shaft 20 and after the rear end face of the outer drive shaft 30. If the inner drive shaft 20 moves forward in the outer drive shaft 30 and the stop element 51 is in the locked position, it is reached that the inner drive shaft 20 hits the stop element 51 with its shoulder 28 in particular and the stop element 51 again To the extent that its front side hits the rear side of the outer drive shaft 30. Due to the double stop, the stop element 51 prevents further axial movement of the inner drive shaft 20 forward relative to the outer drive shaft 30, that is, the stop element 51 limits the inner drive shaft 20 in the outer drive shaft 30. It moves axially and can transmit a forward axial force from the inner drive shaft 20 to the outer drive shaft 30 via the stop element 51. FIG. 4 shows the stop element 51 in the locked position, the shoulder 28 stopped on the stop element 51, and the outer drive shaft 30 stopped on the stop element 51. In this state, the inner drive shaft 20 protrudes forward beyond the outer drive shaft 30 by one step.
在殼體40中構造用於容納止擋元件51的容納部45，容納部沿徑向在外側鄰接貫通孔41。在止擋元件51沿軸向到達容納部45面前時，止擋元件51能夠在徑向向外進入容納部45的運動中進入釋放位置中。在釋放位置中，止擋元件51與兩個內驅動軸20和外驅動軸30沿徑向錯開，使得內驅動軸20和外驅動軸30在釋放位置中不再能夠止擋在止擋元件51上且止擋元件51因此不再限制兩個內驅動軸20和外驅動軸30相對彼此的軸向相對運動。尤其在釋放位置中也不再將向前的軸向力從內驅動軸20經由止擋元件51傳遞到外驅動軸30上。圖5示出了在止擋元件51恰好進入容納部45且進入釋放位置中之後所出現的狀態下的安置設備1。 A receiving portion 45 for receiving the stop element 51 is formed in the housing 40, and the receiving portion adjoins the through hole 41 on the outside in the radial direction. When the stop element 51 reaches the front of the receiving portion 45 in the axial direction, the stop element 51 can enter the release position during the movement radially outward into the receiving portion 45. In the released position, the stop element 51 is radially offset from the two inner drive shafts 20 and the outer drive shaft 30, so that the inner drive shaft 20 and the outer drive shaft 30 can no longer stop at the stop element 51 in the released position. The upper and stop element 51 therefore no longer restricts the axial relative movement of the two inner drive shafts 20 and the outer drive shafts 30 relative to each other. Especially in the release position, forward axial forces are no longer transmitted from the inner drive shaft 20 via the stop element 51 to the outer drive shaft 30. FIG. 5 shows the setting device 1 in a state that occurs after the stop element 51 has just entered the receiving portion 45 and into the release position.
如尤其圖3所示，在所示實施方式中，止擋元件51構造成打開的環，凸肩28構造成環形凸肩並且容納部45構造成環形。但是也可為其他的設計方案。尤其在所示的實施方式中，止擋元件51構造成彈簧，這能夠藉助彈簧力使得止擋元件51自動地進入容納部45中以及釋放位置中，該彈簧力存儲在止擋元件51本身中。但是原則上也可 考慮具有非彈性的止擋元件51以及額外的彈簧的布置方式。 As shown in particular in FIG. 3, in the embodiment shown, the stop element 51 is configured as an open ring, the shoulder 28 is configured as an annular shoulder, and the receptacle 45 is configured as a ring. But other designs are also possible. In particular, in the embodiment shown, the stop element 51 is configured as a spring, which enables the stop element 51 to automatically enter the receiving portion 45 and into the release position by means of a spring force, which spring force is stored in the stop element 51 itself . However, in principle, arrangements with non-resilient stop elements 51 and additional springs are also conceivable.
在外驅動軸30的前端面上構造具有齒部的攜動構型33，攜動構型為了在外驅動軸30和待安置的膨脹錨栓10的膨脹套筒11之間的不可相對轉動的耦合而能夠接合入膨脹錨栓10的膨脹套筒11上的對應的構型中。 A driving configuration 33 with teeth is formed on the front face of the outer drive shaft 30. The drive configuration is for the non-rotatable coupling between the outer drive shaft 30 and the expansion sleeve 11 of the expansion anchor 10 to be placed. It can be engaged into a corresponding configuration on the expansion sleeve 11 of the expansion anchor 10.
圖4至圖6示出了安置設備1在根據本發明的安置方法的依次連續不同的階段中。尤其圖4示出了安置設備1在安置方法的第一階段開始時的狀態。在該狀態中，鎖止裝置以其止擋元件51處於鎖止位置中，外驅動軸30經由止擋元件51沿軸向貼靠在內驅動軸20的凸肩28上，內驅動軸20在前側在構成銷的情況下突出超過外驅動軸30一段。膨脹錨栓10的膨脹套筒11被推到多個銷上，其中，銷伸入構造在膨脹套筒11內部中的膨脹通道12中，確切地說，銷伸入如此深，以致於膨脹套筒11的後端面貼靠在外驅動軸30上且接入外驅動軸30的攜動構型33中。較佳地，該布置如此確定尺寸，亦即，在該狀態下由內驅動軸20構成的銷貼靠在膨脹錨栓10的布置在膨脹錨栓10的膨脹通道12中的膨脹體15上或至少沒有離開膨脹體過遠。 4 to 6 show the installation device 1 in successively different stages of the installation method according to the invention. In particular, FIG. 4 shows the state of the installation device 1 at the beginning of the first phase of the installation method. In this state, the locking device is in its locked position with its stop element 51, the outer drive shaft 30 is axially abutted against the shoulder 28 of the inner drive shaft 20 via the stop element 51, and the inner drive shaft 20 is at The front side protrudes beyond the outer drive shaft 30 by a section of the pin. The expansion sleeve 11 of the expansion anchor 10 is pushed onto a plurality of pins, wherein the pins extend into the expansion channel 12 formed in the interior of the expansion sleeve 11. To be precise, the pins extend so deep that the expansion sleeve The rear end surface of the barrel 11 abuts on the outer drive shaft 30 and is inserted into the driving configuration 33 of the outer drive shaft 30. Preferably, the arrangement is dimensioned such that, in this state, the pin constituted by the inner drive shaft 20 bears against the expansion body 15 of the expansion anchor 10 arranged in the expansion channel 12 of the expansion anchor 10 or At least not far from the expansion body.
此時，安置設備1在其殼體40的前側處置於基礎6上且內驅動軸20藉助衝擊鑽機進行旋轉衝擊運動。內驅動軸20的轉動運動經由周齒32傳遞給外驅動軸30並且從外驅動軸又經由攜動構型33傳遞到膨脹錨栓10的膨脹套筒11上。內驅動軸20向前的衝擊運動經由止擋元件51沿鎖 止方向傳遞到外驅動軸30上且從外驅動軸又經由其前端面傳遞到膨脹套筒11上。由此膨脹套筒11在安置方法的第一階段藉由安置設備1旋轉衝擊地運動且在這種情況下鑽入基礎6中。 At this time, the setting device 1 is disposed on the foundation 6 on the front side of its housing 40 and the inner drive shaft 20 performs a rotary impact motion by means of an impact drill. The rotational movement of the inner drive shaft 20 is transmitted to the outer drive shaft 30 via the peripheral teeth 32 and from the outer drive shaft to the expansion sleeve 11 of the expansion anchor 10 via the driving configuration 33. The forward impact motion of the inner drive shaft 20 is transmitted to the outer drive shaft 30 via the stop element 51 in the locking direction, and from the outer drive shaft to the expansion sleeve 11 via its front end surface. As a result, the expansion sleeve 11 is moved rotationally and impactally in the first stage of the installation method by the installation device 1 and in this case is drilled into the foundation 6.
在膨脹套筒11鑽入基礎6中時，內驅動軸20、外驅動軸30和沿軸向在這兩個內驅動軸20和外驅動軸30之間在徑向上與內驅動軸20和外驅動軸30重疊的止擋元件51相對於殼體40沿軸向向前運動。內驅動軸20和外驅動軸30以及止擋元件51進行運動，直至止擋元件51在軸向上與容納部45重疊地位於殼體40中。由於彈簧力，止擋元件51此時沿徑向向外彈入容納部45中以及止擋元件51的釋放位置中。在該釋放位置中止擋元件51與兩個驅動軸中的至少一個，較佳與兩個內驅動軸20和外驅動軸30的徑向重疊取消。由此也取消了從內驅動軸20開始到外驅動軸30以及膨脹錨栓10的膨脹套筒11的軸向力傳遞。由此安置方法的第一階段自動結束且第二階段開始。所得到的階段在圖5中示出。 When the expansion sleeve 11 is drilled into the foundation 6, the inner drive shaft 20, the outer drive shaft 30, and the axial direction between the two inner drive shafts 20 and the outer drive shaft 30 are radially with the inner drive shaft 20 and the outer The stop element 51 overlapping the drive shaft 30 moves forward with respect to the housing 40 in the axial direction. The inner drive shaft 20 and the outer drive shaft 30 and the stop element 51 are moved until the stop element 51 is located in the housing 40 in the axial direction overlapping with the receiving portion 45. Due to the spring force, the stop element 51 springs radially outwards into the receptacle 45 and into the released position of the stop element 51 at this time. In this release position, the radial overlap of the stop element 51 and at least one of the two drive shafts, preferably with the two inner drive shafts 20 and the outer drive shaft 30 is cancelled. This also eliminates the transmission of axial forces from the inner drive shaft 20 to the outer drive shaft 30 and the expansion sleeve 11 of the expansion anchor 10. The first phase of the placement method thus ends automatically and the second phase begins. The resulting phases are shown in FIG. 5.
在第二階段中，由衝擊鑽機加載的內驅動軸20還實施旋轉衝擊運動。但是因為鎖止裝置此時處於釋放位置中，僅還將內驅動軸20的轉動運動傳遞給膨脹套筒11，亦即，還經由周齒32傳遞到外驅動軸30且從外驅動軸經由攜動構型33傳遞到膨脹套筒11。而內驅動軸20的衝擊運動不再傳輸到膨脹套筒11上，因為內驅動軸20和外驅動軸30在軸向方向上不再彼此貼靠。因此，膨脹套筒11在第二階 段中基本僅還實施轉動運動。但是因為基於鎖止裝置的釋放狀態，內驅動軸20此時能夠相對於外驅動軸30沿軸向向前運動，內驅動軸20在第二階段中衝擊地加載膨脹錨栓10的膨脹體15且在轉動的膨脹套筒11的膨脹通道12中推動膨脹體15向前。對此，膨脹體15到達膨脹通道12的前部的逐漸變細的區域中，在此膨脹體15沿徑向擴張膨脹套筒11。該擴張與膨脹套筒11的轉動運動結合，在膨脹套筒11的前部區域的高度上產生在基礎6中的底切部，膨脹套筒11成型到該底切部中。較佳在內驅動軸20的在第一階段中間接地，即經由止擋元件51撞擊在外驅動軸30上的凸肩28此時直接撞擊在外驅動軸30上時及/或在相對於殼體40向後錯開地布置在內驅動軸20上的另一凸肩27在後側撞擊在殼體40上時，第二階段結束。所得到的狀態在圖6中示出。 In the second phase, the inner drive shaft 20 loaded by the impact drill also performs a rotary impact motion. However, because the locking device is in the released position at this time, only the rotational movement of the inner drive shaft 20 is transmitted to the expansion sleeve 11, that is, it is also transmitted to the outer drive shaft 30 via the peripheral teeth 32 and from the outer drive shaft via the portable shaft. The moving configuration 33 is transmitted to the expansion sleeve 11. The impact motion of the inner drive shaft 20 is no longer transmitted to the expansion sleeve 11 because the inner drive shaft 20 and the outer drive shaft 30 are no longer in contact with each other in the axial direction. Therefore, in the second stage, the expansion sleeve 11 basically only performs a rotational movement. However, based on the released state of the locking device, the inner drive shaft 20 can now move forward in the axial direction relative to the outer drive shaft 30, and the inner drive shaft 20 impactally loads the expansion body 15 of the expansion anchor 10 in the second stage. And the expansion body 15 is pushed forward in the expansion channel 12 of the rotating expansion sleeve 11. For this purpose, the expansion body 15 reaches a tapered region in front of the expansion channel 12, where the expansion body 15 expands the expansion sleeve 11 in the radial direction. This expansion is combined with the rotational movement of the expansion sleeve 11 to create an undercut in the base 6 at the height of the front region of the expansion sleeve 11, into which the expansion sleeve 11 is shaped. Preferably, the shoulder 28 of the inner drive shaft 20 is grounded in the middle of the first stage, that is, the shoulder 28 that hits the outer drive shaft 30 via the stop element 51 at this time directly hits the outer drive shaft 30 and / or relative to the housing 40 When the other shoulder 27 arranged on the inner drive shaft 20 staggered rearward hits the housing 40 on the rear side, the second stage ends. The obtained state is shown in FIG. 6.
由此，藉由根據本發明的安置設備1能夠藉助連續的安置方法製造鑽孔，安置膨脹錨栓10且製造底切部。對此，藉由安置設備1確保安置深度和膨脹度，使得提供特別高的用戶滿意度和可靠性。藉由底切的原理，能夠在埋入深度相同的情況下有規律地傳遞較高的負荷。 As a result, with the installation device 1 according to the invention, it is possible to manufacture drill holes, to install the expansion anchor 10 and to produce undercuts by means of a continuous installation method. In this regard, the placement device 1 ensures the placement depth and expansion, so that particularly high user satisfaction and reliability are provided. With the principle of undercutting, it is possible to regularly transmit higher loads with the same burial depth.
膨脹體15較佳具有自鎖角，使得安置設備1在膨脹套筒11的擴張完成之後能夠被移除，但是膨脹套筒11沒有再次回到其初始位置中。在安置方法結束之後，可例如將螺栓安置在膨脹錨栓10中的布置在膨脹套筒11上的指向膨脹通道12中的內螺紋上。 The expansion body 15 preferably has a self-locking angle so that the setting device 1 can be removed after the expansion of the expansion sleeve 11 is completed, but the expansion sleeve 11 does not return to its initial position again. After the end of the installation method, a bolt can be placed, for example, on an internal thread of the expansion anchor 10 which is arranged on the expansion sleeve 11 and points in the expansion channel 12.
為了在安置方法的第二階段結束之後使得安置設備1能夠再次回到初始狀態以用於另一安置，可在用於止擋元件51的容納部45中設置一個或多個複位元件48，藉助複位元件可使止擋元件51沿徑向向內移動。在該實施例中設置兩個叉形的複位元件48，其分別具有突出到殼體40外部的複位按鈕。 In order to enable the setting device 1 to return to the initial state again for another setting after the end of the second phase of the setting method, one or more reset elements 48 may be provided in the receiving portion 45 for the stop element 51, The stop element 51 can be moved radially inwardly by means of the reset element. In this embodiment, two fork-shaped reset elements 48 are provided, each of which has a reset button protruding to the outside of the housing 40.
如尤其圖1和圖2所示，內驅動軸20在前部區域中實施成向前敞開的空心軸。經由該空心軸能夠將在安置進程期間掉落的鑽屑運走。在殼體40之後在內驅動軸20上設置回轉通道49，藉助回轉通道又能夠將材料從空心軸中運走。 As shown in particular in FIGS. 1 and 2, the inner drive shaft 20 is designed as a hollow shaft that opens forward in the front region. Via this hollow shaft, drill cuttings that fall during the installation process can be carried away. A rotary passage 49 is provided on the inner drive shaft 20 behind the housing 40, and the material can be removed from the hollow shaft by the rotary passage.
圖7示出了膨脹錨栓10的細節視圖。如在圖7中可看出地，膨脹套筒11的前端面構成尖端，亦即，其具有小於180°、較佳約120°的張角。膨脹錨栓10的膨脹套筒11在其外側上不僅具有端面側的第一切削刃17而且具有周向側的第二切削刃18，端面側的切削刃輔助膨脹套筒11的鑽孔過程，周向側的切削刃輔助膨脹套筒11的擴張。特別較佳的是，膨脹套筒11配備有切削體19，其較佳由硬質合金構成，其中，較佳在切削體19上分別構成端面側的第一切削刃17和周向側的第二切削刃18。在所示的實施例中，膨脹套筒11和切削體19是單獨的零件。但是切削體也可為膨脹套筒11的有針對性地硬化的區域。膨脹套筒11在其後部，亦即，在與尖端相對的端面上具有用於安置設備1的攜動構型33的配合構型。 FIG. 7 shows a detailed view of the expansion anchor 10. As can be seen in FIG. 7, the front face of the expansion sleeve 11 constitutes a tip, that is, it has an opening angle of less than 180 °, preferably about 120 °. The expansion sleeve 11 of the expansion anchor 10 has not only a first cutting edge 17 on the end surface side but also a second cutting edge 18 on the outer side on the outer side. The cutting edge on the end surface side assists the drilling process of the expansion sleeve 11. The cutting edge on the circumferential side assists the expansion of the expansion sleeve 11. It is particularly preferred that the expansion sleeve 11 is provided with a cutting body 19, which is preferably composed of a cemented carbide. Among them, the cutting body 19 preferably constitutes a first cutting edge 17 on the end face side and a second cutting edge 17 on the circumferential side. Cutting edge 18. In the embodiment shown, the expansion sleeve 11 and the cutting body 19 are separate parts. However, the cutting body can also be a targeted hardened region of the expansion sleeve 11. The expansion sleeve 11 has, at its rear portion, that is, on the end surface opposite the tip, a mating configuration for accommodating the driving configuration 33 of the device 1.
為了在藉由膨脹體15使膨脹套筒11轉動且擴張時能夠製造錐形的底切部，周向側的第二切削刃18沿著膨脹錨栓10的縱軸線100，特別較佳如所示地與該縱軸線100平行地延伸。沿縱軸線100的方向看，周向側的第二切削刃18部分地與膨脹通道12重疊。尤其沿著縱軸線100看，周向側的第二切削刃18布置在膨脹通道12的前端部區域的高度上，在該前端部區域中膨脹通道12的橫截面朝向膨脹通道12的前端部減小。 In order to be able to produce a tapered undercut when the expansion sleeve 11 is rotated and expanded by the expansion body 15, the second cutting edge 18 on the circumferential side is along the longitudinal axis 100 of the expansion anchor 10, which is particularly preferred as required The illustration extends parallel to the longitudinal axis 100. Seen in the direction of the longitudinal axis 100, the second cutting edge 18 on the circumferential side partially overlaps the expansion channel 12. Viewed in particular along the longitudinal axis 100, the second cutting edge 18 on the circumferential side is arranged at the height of the front end region of the expansion channel 12, in which the cross section of the expansion channel 12 decreases toward the front end of the expansion channel 12. small.
